Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
The central cooling system of studying is at present applicable to bulk freighter, and power system capacity is larger, adopts the real boatman's condition checking of prior art, has following shortcoming:
First,, for the model machine of installing at real ship, need to find the boats and ships of suitable cooling system capacity so that installation test model machine.And because cooling device quantity is more, the quantity of the each cooling device of real ship and capacity and model machine along with different shipowners' demand is different and slightly variant with equipment manufacturer's configuration, need by a certain proportion of conversion, make the system of research suitable with the system experimentation data of real ship.In addition, the system running state under Various Seasonal is if desired verified in the test of real ship, need collection model machine service data under each research experimental tests ocean temperature under each seasons such as spring, summer, autumn and winter generally to consider the variation of extraneous ocean temperature due to needs, the cycle of test is longer.And send work because real ship has public affair, and cannot be undertaken by expection plan for the debugging of model machine, there is larger restriction for the research of project.
Secondly, for the model machine installation of test site on the bank, to having relatively high expectations of test site.And use part cooling pump and the cooling device used with development test, and being only applicable to model machine, cannot in sundry item, again utilize, this input cost to model machine is larger, larger for the expense of project research.
So, for the problem running in above two kinds of processs of the test, the present invention proposes to adopt the model of cooling system contracting ratio, running situation under place simulation Various Seasonal, different operating mode on the coast, ensure the reliability of central cooling system, the operation of validity, can make again the cost of test method.
Concrete implementation process is as follows:
First this experimental prototype dwindles studied central cooling system according to a certain percentage, and this can not only reduce greatly the purchase cost of model machine, has also reduced the requirement of test site on the bank simultaneously.Secondly simplify the system configuration of model machine, the requirement of for subsequent use and maintainability of boats and ships is not considered in the configuration of all devices.Concrete configuration is as follows:
This experimental prototype and research object system are dwindled according to the ratio of 1:40, and the place capacity such as cooling sea water pump, fresh water cooling pump, central cooler, fresh-water cooler is dwindled according to this ratio.This model machine is furnished with 2 cooling sea water pumps (for subsequent use each other), 1 fresh water cooling pump, 1 central cooler, 1 sea chest, test site is furnished with the steam boiler of 1 6t, 1 shell-and-tube heater, 1 sea water pump, 1 fresh water hot water tank, and 1 seawater pond, and connect respective line, valve member and control annex etc.This model machine comprises cooled with seawater pipeline and fresh water cooling line.
In cooled with seawater pipeline, sea water pump sucks seawater from seawater pond, enter sea chest through shell-and-tube heater, and in sea chest cooling temperature control to the ocean temperature under corresponding season environment, cooling sea water pump sucks refrigerated sea water from sea chest, is back to seawater pond cooling after central cooler and fresh water heat exchange.Wherein, shell-and-tube heater is set and opens as required, object is in order to regulate ocean temperature, thereby in sea chest, simulates different ocean temperatures; 2 cooling sea water pumps, the capacity of every 100%, wherein 1 for subsequent use, with the switching of simulated seawater pump; Because model machine does not need to arrange the backwash tube of central cooler seawater side, corresponding pipeline can omit, and utilizes the aperture of stop valve to change the resistance of pipeline.
In fresh water cooling line, fresh water pump sucks hot water from fresh water hot water tank, after central cooler and refrigerated sea water heat exchange, is back to fresh water hot water tank.In this fresh water circuit, adopt fresh water hot water tank to replace the various refrigeratorys in fresh water circuit, in fresh water hot water tank, be provided with steam heating coil, the difference by quantity of steam is to simulate the heat load of various differences equipment to be cooled.
The annexes such as valve member, filter, thermometer, tensimeter, temperature-sensing valve such as the corresponding stop valve of supporting configuration, screw down nonreturn valve in cooled with seawater pipeline and fresh water cooling line, and need to configure the control elements such as corresponding pressure transducer, temperature sensor according to system, to realize the object of Work condition analogue.
Cooled with seawater pipeline and fresh water cooling line move simultaneously, simulate respectively boats and ships ruuning situation under Various Seasonal, different operating mode in navigation process, to verify seawaterline and fresh water line effective operation and the economy of central cooling system.
Boats and ships cooling system scale model verification method mainly, by contracting than research model, is simplified the method for Study system, with input cost and practice still less, realizes the running situation checking under complex working condition.
This simulation verification method can the rest may be inferred be applied to the checking after the optimization of boats and ships other system improves, as ballast for cruising system, watercraft engine room ventilating system etc.Make deviser after theoretical research, can conditional pass test reliably the actual effect of carrying out after verification system optimization, the validity of proof theory research.The present invention has significantly reduced operating cost and the test institute elapsed time of test, makes more easily to carry out with verification experimental verification theoretical research.
Complicated test also can be verified by suitable research software.Boats and ships cooling system also can carry out demonstration test situation by the simulation software such as flowmaster or aft.Software is by system modeling, and to input known parameters be prerequisite, and the operation of analogue system, simplifies the theoretical a kind of method that obtains fast result of calculation of calculating.
Because the installation question running in operational process for actual product, debugging problem and Solve on site method etc. cannot directly be determined by software emulation, so be necessary by contracting than the actual motion of PM prototype model.In conjunction with the calculating of simulation software, can better carry out simplation verification to the operating mode of integral central cooling water system for marine diesel engine simultaneously.
The present invention is mainly by the configuration of studied cooling system contracting according to a certain percentage ratio, and in the situation that not affecting systematic study function, the equipment Pipe-Line of the required outfit of simplification system.And with content most economical, that test simulation is studied the most intuitively.
